Abstract

A method for calibrating is provided, including receiving, for each of a plurality of frequencies, an indication of a characteristic value of a position sensor for placement in a patient; measuring an actual value of the position sensor at each of the plurality of frequencies; and determining, at each of the plurality of frequencies, calibration data indicative of a deviation of the actual value from the characteristic value. <??>Said value can represent the gain, the position, the orientation or the alignment of the sensor. The position sensor comprises one or more coils, typically three orthogonal coils. <IMAGE>
